Multimeter Buyers’ Guide
A multimeter is a handheld tool that is used by electricians and other types of technicians to measure and test various electrical components. It is a great tool for people carrying out DIY work and hobbyists too. There are lots of different multimeters on the market so this buyer’s guide is a quick and easy way to narrow down the choice to find the best multimeter for your uses.
Analog vs Digital
This is one of the first decisions you will need to make when choosing a multimeter as they are available in analog or digital form. Digital multimeters are more popular but some people do prefer the clarity of an analog display. Some electricians feel it is easier to see the trends and real-time changes with an analog multimeter but they have a lower input impedance and are usually more limited in what they can measure compared to a digital option. Generally, the best options are digital multimeters as they are much more versatile and efficient.
If you’re not sure whether the multimeter you are considering is digital or analog it is simple to tell the difference as a digital multimeter has a small screen to display the reading while an analog multimeter has a needle that moves along a scale.
RELATED:
Auto or Manual Ranging
- An auto ranging digital multimeter has the ability to recognise what is being tested and will display the desired measurement. Choosing an auto-ranging option can save you time and means you can use the multimeter without knowing all the ins and outs of how it works.
- Manual ranging multimeters feature preset ranges and you will need to know the range of values the component comes under in order to be able to get a reading.
Key Features
If you have a clear idea of what you will need to measure and test it will be easier for you to choose between different multimeters but if you are looking for a good all-rounder keep in mind the following features:
Versatility
Basic multimeters are generally able to measure AC current, DC current, voltage, resistance and capacitance. The best electrical multimeter options offer a wider variety of measurements and tests including diode, continuity, battery and transistor tests as well as functions such as auto range, true RMS and an analog bar graph. The functions are important to consider, make sure the multimeter you choose is able to produce accurate measurements and tests in the areas you require them.
Design & Build
Most multimeters come in a sturdy casing and are brightly coloured to prevent accidents. The build needs to be of high quality to withstand regular use. The majority of multimeters can be held comfortably in one hand and some come with a magnetic hook or a kickstand to make it easier for you to carry out the measurements and tests.
RELATED:
Accuracy
The accuracy of the multimeter is the largest allowable error under specific conditions, what is considered acceptable will generally vary depending on the situation. As a broad guideline, +/- 2% is fine for home hobby uses. In professional situations, the best multimeters are going to be the more accurate ones but these will also come at a higher cost.
Safety Features
The majority of multimeters have a warning feature where they will beep or buzz if the leads are plugged in incorrectly for the settings that are being used. This helps prevent a short circuit from occurring by incorrectly using the multimeter. Always check the multimeters maximum voltage and current ratings to make sure it can handle what you need to use it for.
